Hi: I am using an RSP-1 and SDRuno to attempt to receive WX satellite photos...Most of my pictures are full of some sort of artifact that I cannot identify...I am wondering if anyone has any suggestions as to the setting in SDRuno that I should be using...I realize that every setup is different, but I am wondering if there are any common denominators that may help me? Could I be overdriving the reception? Should the volume into the decoding software (WXtoIMG) be higher or lower...Is it better to overdrive a bit or under drive? I have been running at about 50% volume...If I go below about 40% no image at all appears...Above 50% and the artifact appears...Any basic suggestions or guidance will be most welcome! Is there an easier program to begin with than WXtoIMG?...Thanks for your advice!

It sounds like sound enhancement is enabled in your soundcard. It is enabled by default on some systems. I have a Creative soundcard, on it the special effects are called EAX effects. They must be disabled when decoding FAX or any other digital signals.

There is a level meter on the lower right side in Wxtoimg. I try to keep it in the green zone. You can run a manual recording test by recording background noise using the mode and bandwidth settings normally used for reception. The background noise will be a slightly greater amplitude than actual Sat signal reception. I usually try to keep it around 60-70%.

The LNA gain is something you'll have to tinker with. I usually have it set to maximum but back it off one click if there is any overload. I also have an inline LNA mounted at the antenna - It's a Radio Shack TV antenna signal booster.

Run Wxtoimg. Select File----Mixer Control in Wxtoimg. Your PC's list of recording options will appear. If 'What You Hear' or 'Stereo Mix' is not shown, it is either not supported or disabled. See this link to enable it (if disabled):

Hello, the other question I have relates to WxToImg and CubicSDR. I was reading something in the info of WxToImg that the satellite signals are in Narrow FM mode, however, when I select that option, i get nothing but static even when one of the NOAA satellites are within reception range. but if I select LSB, the signal can be easily heard. Do I need to change some setting in CubicSDR for the signal to be heard in NFM??? Maybe change the IF or something else?

Also, what is the purpose of the 'center frequency' in Cubic SDR?? I found some webpage that explains how to change the center frequency, but it does NOT explain the function of the center frequency.

Narrow band FM mode is too narrow, if using SDRuno. To properly receive the FM signal from NOAA orbital weather satellites, taking into account Doppler shift during the pass plus the bandwidth of the signal, you should have a bandwidth setting on your receiver of around 50kHz. In SDRuno, this is achieved by selecting WFM and then slightly narrowing the bandwidth from 60kHz to around 50kHz in the AUX SP window (select and drag the edge of the shown bandwidth area). Also, WXtoIMG generally requires the audio output from the receiver software (e.g., SDRuno or equivalent) to be looped back to the audio input so that WXtoIMG can receive it.
